So far, so good.

That's the message from Streets Commissioner David Perri regarding the snowstorm blanketing Philadelphia right now, just two days after a different storm dropped a half-foot on some parts of the city.

"Some of the streets are just wet. Other streets have a small accumulation of slush," Perri said. "We simply don't have the snow depths on the streets at this point to warrant plowing."

Perri said 176 city vehicles are scattering salt now to prevent freezing on the roads tonight. But they won't start a full-blown plowing operation until snow depths on the streets exceed two inches.

The worst of the storm is expected to be over by early afternoon, Perri said.

Mayor Nutter talked about the city's preparations for the storm yesterday but will not be unavailable to comment today, administration spokesman Mark McDonald said.

Nutter was at the White House this morning for a meeting on climate change, according to a Twitter post by a city official.

Perri said he has communicated with the mayor via email this morning.

Accompanying Nutter at the White House was Sam Phillips, deputy managing director for the Office of Emergency Management.

UPDATE: Nutter spokesman Mark McDonald sent a statement from the White House regarding the meeting Nutter attended this morning.

"On Tuesday, December 10th, the White House will host the first meeting of the State, Local, and Tribal Leaders Task Force on Climate Preparedness and Resilience, which the President established last month to advise the Administration on how the Federal Government can respond to the needs of communities nationwide that are dealing with extreme weather, sea level rise, and other impacts of climate change. This meeting will focus on building climate resilience into efforts to better prepare for and recover from natural disasters. In addition, Task Force members will have the opportunity to share their expertise and experience in implementing climate preparedness measures, and begin to consider recommendations for the President. Administration officials scheduled to participate include Council on Environmental Quality Chair Nancy Sutley, Director of Intergovernmental Affairs David Agnew, Secretary of Transportation Anthony Foxx, Secretary of Housing and Urban Development Shaun Donovan, and FEMA Associate Administrator David Miller."
